Subject: [PATCH] HPack: fix incorrect integer overflow check
|
|
|
|
This code never worked:
|
|
|
|
For the comparison with max() - 32 to trigger, on 32-bit platforms (or
|
|
Qt 5) signed interger overflow would have had to happen in the
|
|
addition of the two sizes. The compiler can therefore remove the
|
|
overflow check as dead code.
|
|
|
|
On Qt 6 and 64-bit platforms, the signed integer addition would be
|
|
very unlikely to overflow, but the following truncation to uint32
|
|
would yield the correct result only in a narrow 32-value window just
|
|
below UINT_MAX, if even that.
|
|
|
|
Fix by using the proper tool, qAddOverflow.
|
|
|
|
Manual conflict resolutions:
|
|
- qAddOverflow doesn't exist in Qt 5, use private add_overflow
|
|
predecessor API instead
|
|
|
